当我想从我的应用程序graph.windows.net/{aadDirectoryId}/users/{userId.Value}/$links/memberOf?api-version=1.6从图api中获取成员时
我总是得到

当我打电话给https://graphexplorer.azurewebsites.net/时,一切都很好。
在azure AD中,我为api permission设置了权限
通话代码:
private static List<string> GetGroupsFromGraphAPI(ClaimsIdentity claimsIdentity)
{
_logger.Info($"Getting claims from Graph API for {claimsIdentity.Name}.");
List<string> groupObjectIds = new List<string>();
var aadClientId = ConfigurationManager.AppSettings["ida:ClientId"];
var aadSecret = ConfigurationManager.AppSettings["ida:ClientSecret"];
var aadDirectoryId = ConfigurationManager.AppSettings["ida:DirectoryId"];
ClientCredential credential = new ClientCredential(aadClientId, aadSecret);
AuthenticationContext authContext = new AuthenticationContext("https://login.microsoftonline.com/" + aadDirectoryId);
string accessToken;
try
{
_logger.Info($"Client ID: {aadClientId}");
_logger.Info($"Secret: {aadSecret}");
_logger.Info($"Directory id: {aadDirectoryId}");
var token = authContext.AcquireToken("https://graph.windows.net", credential);
_logger.Info($"Token: {token.ToString()}");
accessToken = token.AccessToken;
_logger.Info($"Get access token {accessToken}");
}
catch
{
_logger.Error("Cannot aquire token for Graph API.");
throw;
}
var userId = claimsIdentity.FindFirst("http://schemas.microsoft.com/identity/claims/objectidentifier");
if (userId == null)
{
_logger.Warn($"No user ID to get group membership for. ({claimsIdentity.Name})");
return groupObjectIds;
}
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
HttpResponseMessage response;
try
{
var link =
$"https://graph.windows.net/{aadDirectoryId}/users/{userId.Value}/$links/memberOf?api-version=1.6";
_logger.Info($"GetAsync {link}");
response = client.GetAsync(link).Result;
}
catch
{
_logger.Error("Failed to load group membership for " + claimsIdentity.Name);
throw;
}
}
Forbidden
错误和需要管理员同意
查看已共享以获取令牌的代码,您正在使用应用程序标识,因此应用程序所需的权限将是应用程序权限。
ClientCredential credential = new ClientCredential(aadClientId, aadSecret);
AuthenticationContext authContext = new AuthenticationContext("https://login.microsoftonline.com/" + aadDirectoryId);
...
var token = authContext.AcquireToken("https://graph.windows.net", credential);
在屏幕截图中,您已选择了Azure AD图表的Directory.Read.All
权限,但它也表示管理员同意未完成。如果您查看权限,它会清楚地说明,管理员同意是否为是。
因此,您的解决方案是授予管理员同意以获得所需的许可。如果您以管理员身份登录,则可以直接从Azure门户(您已分配权限的同一页面)执行此操作。另一种方法是使用AdminConsent Endpoint
https://graphexplorer.azurewebsites.net/
Azure AD Graph Explorer正在使用Delegated Permissions
并以登录的用户身份调用API,因此它正在为您工作。虽然您尝试从应用程序中执行相同的操作,但不同之处在于您使用应用程序的身份进行调用,但尚未同意权限。https://graph.windows.net
,因此您的应用程序只需要Azure AD Graph API
的权限。您可以安全地删除为Microsoft Graph API
分配的权限(除非您在应用程序的其他位置使用Microsoft Graph API)
